I installed this muffler on my car and was blown away by the improved sound and horsepower. As a result of my tests, I determined that this muffler greatly enhances the performance of my vehicle. The installation process was straightforward and the quality of the construction is excellent. The only downside is that it is a bit pricier than some other mufflers on the market, but the difference in performance and sound is worth it. Overall, I highly recommend this muffler to any performance car enthusiast.
